Scaffolds encapsulating BMP-hBMSCs showed much higher ALP activity and OCN deposition in the matrix. a ALP staining of the constructs in the Protein and Gene groups after 14 days of culture. The purple staining indicated the presence of ALP. b OCN deposition was detected by IHC in both groups after 14 days of culture. The brown staining, indicated by arrows, indicates OCN-positive deposition. Bar = 100 μm
